So, you're in a room in which there are two doors, a red one and a blue one. If you go out one door, then you will be free, but if you go out the other one then you will die instantly. You don't know which is which, and won't know until you go out a door. The only other thing in the room with you is a two-headed turtle. One head always lies, and the other head always tells the truth but you don't know which is which. You can only ask one head one question. What question do you ask which head?

The turtle is not going to leave the room, he is not going to say anything unless you ask him something, he is too big to kick or throw out one of the doors, there is not a window in the room, and you do not have anything on you that will help.
